As can be seen in connection with fig. 1-5, the optical module 1 comprises a mounting assembly (not shown) and at least a first optical element 100 mounted to a first mounting frame 21.

The mounting assembly of the optical element includes:

a mounting base 10, comprising a first mounting plate 11 and a second mounting plate 12 intersecting with and fixedly connected to the first mounting plate 11, the first mounting plate 11 comprising a first window 110, the second mounting plate 12 comprising a second window 120, the first mounting plate 11 comprising a first threaded hole 111 and a second threaded hole 112;

a first mounting frame 21 for mounting at least one first optical element 100, the first mounting frame 21 including a third window 210;

m elastic tension members (not shown), wherein the first mounting frame 21 is inclined to the first mounting plate 11 and the second mounting plate 12 and is elastically connected with the mounting seat 10 through the M elastic tension members, and M is a positive integer; and

A first adjusting screw C1 and a second adjusting screw C2, wherein the first adjusting screw C1 passes through the first threaded hole 111 and then abuts against a first position P1 of the first mounting frame 21, and the second adjusting screw C2 passes through the second threaded hole 112 and then abuts against a second position P2 of the first mounting frame 21;

the second mounting plate 12 is rotatably contacted with a third position P3 of the first mounting frame 21, and the first position P1, the second position P2 and the third position P3 are distributed in a triangle shape.

Specifically, the mounting base 10 is formed by fixedly connecting a first mounting plate 11 and a second mounting plate 12 in a crossing manner, and a crossing line (not shown) is formed at the crossing portion. Typically, the first mounting plate 11 and the second mounting plate 12 are perpendicular or substantially perpendicular. The extending direction of the intersecting line is a first direction Y, the normal direction of the first mounting plate 11 is a second direction X, and the normal direction of the second mounting plate 12 is a third direction Z. The first mounting plate is parallel to the XZ plane and the second mounting plate is parallel to the XY plane. The mount 10 is L-shaped as seen along the first direction Y. The first screw hole 111 and the second screw hole 112 each penetrate through the first mounting plate 11.

The first mounting frame 21 is disposed obliquely to the first mounting plate 11 and the second mounting plate 12. That is, the first mounting frame 21 is provided in an area surrounded by the L-shaped structure formed by the first mounting plate 11 and the second mounting plate 12. One end of the first mounting frame 21 is disposed opposite to the first mounting plate 11, and the other end is disposed opposite to the second mounting plate 12. The first mounting frame 21 is elastically connected to the mounting base 10 by M elastic tension members, M being a positive integer. Alternatively, M is 1 or 2 or 3 or 4, etc. The M elastic tension members generate a tensile force to bring the first mounting frame 21 and the mount 10 close to each other. Optionally, the elastic tensioning component is a tension spring or a rubber band, etc. The first mounting frame 21 is parallel to the intersecting line. Alternatively, the first mounting frame 21 may be disposed at an acute angle, such as 30 degrees or 45 degrees or 60 degrees, with respect to the second mounting plate 12, but may be disposed at other angles than 0 and 90 degrees.

The first adjusting screw C1 is matched with the first threaded hole 111, and passes through the first threaded hole 111 to be abutted against the first position P1 of the first mounting frame 21. Generating a pushing force to move the first mounting frame 21 and the mount 10 away from each other when the first adjusting screw C1 is screwed in; when the first adjusting screw C1 is withdrawn, the first mounting frame 21 and the mounting seat 10 approach each other by the tension force generated by the M elastic tension members; at equilibrium, the pushing force and the pulling force are equal. That is, the distance between the first mounting frame 21 and the mount 10 at the first position P1 can be adjusted by operating the first adjusting screw C1. Similarly, the second adjusting screw C2 is matched with the second threaded hole 112, and passes through the second threaded hole 112 to abut against the second position P2 of the first mounting frame 21. Generating a pushing force to move the first mounting frame 21 and the mount 10 away from each other when the second adjusting screw C2 is screwed in; when the second adjusting screw C2 is withdrawn, the first mounting frame 21 and the mounting seat 10 approach each other by the tension force generated by the M elastic tension members; at equilibrium, the pushing force and the pulling force are equal. That is, the distance between the first mounting frame 21 and the mount 10 at the second position P2 can be adjusted by operating the second adjusting screw C2.

The second mounting plate 12 is rotatably contacted with a third position P3 of the first mounting frame 21, and the first position P1, the second position P2 and the third position P3 are distributed in a triangle shape. That is, at the third position P3, the distance between the second mounting plate 12 and the first mounting frame 21 is unchanged, and the distance between the first mounting plate 11 and the first mounting frame 21 is also unchanged. When one or 2 of the first adjusting screw C1 and the second adjusting screw C2 is adjusted, the angle and direction of the plane of the triangle formed by the first position P1, the second position P2 and the third position P3 relative to the angle of the first mounting plate 11 and the second mounting plate 12 are adjustable, so that the inclination angle of at least one first optical element 100 mounted on the first mounting frame 21 can be adjusted.
